Description

Technical Field

[0001] The utility model relates to the technical field of automobile detection, in particular to a protective vehicle driving state simulation test bench. Background Art

[0002] With the continuous development of the automobile industry, automobile safety is a very important part. The safety performance test of the automobile before leaving the factory usually uses a vehicle form state simulation test bench, which can comprehensively test and evaluate the various performances of the automobile by simulating real road conditions. For example, the Chinese patent number CN209182035U discloses a car ABS automobile diagnostic setting and diagnostic comprehensive test bench, which simulates road conditions through four sets of main and auxiliary rollers. The four tires of the car are in contact with the four sets of main and auxiliary rollers, and then the driving mechanism such as the motor is started to drive the rollers to rotate to test the performance of the car. However, during the test, the rotation speed of the rollers is relatively high, and there is a risk that the vehicle will fall off the test bench, which may cause damage to objects and personnel around the test, and there are great safety hazards.

[0003] In order to address the above-mentioned problems, a few test benches have set blocking blocks on the front and rear sides of the main and auxiliary rollers of the automobile to provide buffering when the vehicle detaches. However, since the vehicle needs to drive onto the rollers, the height of the blocking blocks should not be too high, and the speed during the detection process is relatively fast. When detachment occurs, the blocking blocks cannot play a blocking role. Alternatively, some test benches have set blocking piles on the front side of the test bench, but they are basically fixed, which means that the vehicle can only drive in and out of the test bench in one direction, which is more troublesome and increases unnecessary time for vehicle detection. In addition, when not in use, the blocking piles protrude from the test bench area, affecting the normal flow of personnel and detection vehicles in this area. Utility Model Content

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, the detection of vehicle performance requires the use of a vehicle driving status simulation test bench, but the existing test bench does not have a protective device. In extreme cases, the vehicle may detach from the drive roller 6 and drive out of the test bench at high speed, causing damage to personnel and other objects, posing a major safety hazard. A few existing test benches will add blocking blocks on both sides of the drive roller 6, or fix blocking piles on one side of the test bench, but both methods have certain defects. Therefore, the inventor has improved the existing test bench and designed a new test bench, which is explained in detail below with reference to the drawings.

[0030] This embodiment provides a protective vehicle driving state simulation test bench, see Figure 1 First, to install the test bench, it is necessary to pre-dig a foundation pit 2 below the reference plane. The test bench frame 1 is installed at the bottom of the foundation pit 2. The frame 1 is arranged on a rotating table 3, and the rotating table 3 can be driven to rotate by a reducer and gears. This is a prior art and will not be described in detail. A bearing platform 5 is arranged on the rotating table 3, and components such as a driving roller 6 are installed. Specifically, a roller bracket is arranged on the bearing platform 5, and there are four groups of roller brackets. In order to facilitate the testing of the inspection vehicle, the four groups of driving rollers 6 are arranged in a rectangular shape and can carry the four tires of the inspection vehicle. The driving rollers 6 are installed through the roller brackets. The four groups of driving rollers 6 can rotate synchronously with the cooperation of the driving device and the linkage device. The driving method can refer to the driving method in patent CN202221485248.3, and will not be described in detail here.

[0031] However, what is different from the comparative patent is that a plurality of telescopic cylinders 4 are arranged between the rotating table 3 and the load-bearing platform 5, and in order to increase the load-bearing capacity of the load-bearing platform 5, all the gravity of the vehicle to be tested is applied to the driving roller 6 through the four wheels, so the plurality of telescopic cylinders 4 are located directly below the corresponding driving roller 6, and the height of the load-bearing platform 5 can be adjusted by the telescopic cylinders 4, so that the driving roller 6 can be at different heights to adapt to different test vehicles and test environments.

[0032] In the present embodiment, one of the main design points of the present scheme is that, in order to be able to protect the tested vehicle, the test bench also includes a protective component installed below the reference plane on one side of the foundation pit 2, and a plurality of protective components are provided, which are arranged on one side of the foundation pit 2 and are all located on the outside in the width direction of the rectangle formed by the four groups of drive rollers 6. It is sufficient to be arranged on the outside in one of the width directions, that is, when the vehicle is placed on the drive roller 6, the protective component is located in front of the front of the vehicle, and can be blocked on one side of the vehicle's forward direction when the vehicle is detached from the drive roller 6 in extreme cases.

[0033] On the basis of the above arrangement, in order to expand the protection range of the vehicle, combined with Figure 2 , multiple groups of protection components are arranged in an arc shape on one side of the foundation pit 2, and at least two groups are arranged on both sides of the length direction of the four rectangular groups of driving rollers 6, that is, at least two groups are arranged on both sides of the driving roller 6 along the length extension direction of the arrangement. The purpose is to be able to wrap the driving roller 6, thereby expanding the protection range of the detection vehicle, and it is also necessary to ensure that there are enough protection components to improve the protection effect, wherein 8-12 groups of protection components are arranged, and they are evenly distributed in an arc shape on one side of the foundation pit 2, and the outermost protection component does not exceed the driving roller 6 in the length extension direction of the rectangle, that is, the edge protection component is on the outside of the width extension direction of the driving roller 6, to avoid the protection component exceeding the driving roller 6 and failing to play a protective role.

[0034] In this embodiment, combined with Figure 2 and Figure 4 The protection component in this scheme is mainly designed in the form of an electric lifting column, which can be lifted and lowered by electric control, which is convenient and fast. The electric control method adopts the existing technology and will not be described in detail. It is sufficient to achieve lifting. The electric control lifting column 7 includes a fixed end 71 and a lifting end 72. The fixed end 71 is installed below the reference plane, and a plurality of fixing blocks 73 are arranged on the outer edge of the fixed end 71, and are staggered left and right along the length direction of the fixed end 71, which can strengthen the fixing strength between the fixed end 71 and the foundation and improve the stability of the fixed column. The lifting end 72 is telescopically installed in the fixed end 71, and the lifting end 72 for protection can be moved above the reference plane. In order to improve the protection effect, the maximum height that the lifting end 72 can extend is higher than the driving roller 6, ensuring that the tire of the detection vehicle can be blocked. In order to further improve the protection effect, the maximum height that the lifting end 72 can be higher than the reference plane is 80cm-120cm, which blocks the front of the detection vehicle, so that the lifting end 72 can have a larger lifting space and can adapt to the protection of more detection vehicles of different heights.

[0035] On the basis of the above structure, when the vehicle detaches, it will collide with the lifting end 72 of the protective component. In order to reduce the damage between the two, a protective soft cover 74 is provided on the outside of the lifting end 72, and the protective soft cover 74 is installed along the length direction of the lifting end 72, and can be raised and lowered with the lifting end 72. When a collision occurs, the protective soft cover 74 can play a buffering role for the vehicle and the lifting end 72. In order to further improve this effect, a through hole 75 is opened in the length direction of the protective soft cover 74, and the through hole 75 is opened along the circumference of the protective soft cover 74. When a collision occurs, the setting of the through hole 75 can make the buffer cushion deform quickly, thereby ensuring the buffering effect.

[0036] Moreover, the height of the fixed end 71 is also designed to a certain extent, the upper plane of the fixed end 71 is not higher than the reference plane, and the lifting end 72 can be completely retracted below the reference plane, so that the fixed end 71 will not protrude from the reference plane, and the fixed end 71 will not be damaged in the event of a collision, and in the non-test state, the lifting end 72 can be completely retracted below the reference plane, making the test area more tidy and not affecting the travel of people and other vehicles in the area.
